CVE-2024-23241 is a vulnerability identified in Apple tvOS and related Apple operating systems that allows a malicious application to leak sensitive user information. The root cause is improper state management within the operating system, which can be exploited by an app without requiring any privileges or user interaction. This flaw affects multiple Apple platforms including tvOS versions before 17.4, iOS 17.4, iPadOS 17.4, and macOS Sonoma 14.4, all of which have addressed the issue through improved state management in their respective updates. The vulnerability is classified under CWE-922 (Improper Restriction of Operations within the Bounds of a Memory Buffer), indicating that the app may access or disclose data it should not have access to. The CVSS v3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, no user interaction, and limited impact on confidentiality and integrity but no impact on availability. There are no known exploits in the wild at this time, but the potential for sensitive data leakage poses a significant privacy and security risk. This vulnerability could be leveraged by attackers to extract personal or sensitive information from users’ devices, potentially leading to further targeted attacks or privacy violations. The fix involves updating to the latest OS versions where Apple has improved state management to prevent unauthorized data access by apps.

For European organizations, the impact of CVE-2024-23241 primarily concerns the confidentiality and integrity of sensitive user information on Apple devices, particularly Apple TV units used in corporate environments or digital signage, as well as iPhones, iPads, and Macs running the affected OS versions. Leakage of sensitive data could lead to privacy breaches, intellectual property exposure, or unauthorized access to corporate information. Organizations relying on Apple ecosystems for communication, media consumption, or internal applications may face risks of data leakage if unpatched devices are present. Although availability is not affected, the breach of confidentiality can undermine trust, lead to regulatory penalties under GDPR, and cause reputational damage. The absence of required privileges or user interaction makes the vulnerability easier to exploit remotely, increasing the risk profile for enterprises with Apple devices connected to untrusted networks or the internet. The medium severity indicates a moderate but non-negligible threat that should be addressed promptly to avoid escalation or chaining with other vulnerabilities.

1. Immediately update all Apple devices, including Apple TV, iPhones, iPads, and Macs, to tvOS 17.4, iOS 17.4, iPadOS 17.4, and macOS Sonoma 14.4 or later versions where the vulnerability is fixed. 2. Enforce strict mobile device management (MDM) policies to ensure devices remain up to date and restrict installation of untrusted or unnecessary applications. 3. Monitor network traffic and device logs for unusual app behavior or data exfiltration attempts, especially on Apple TV devices used in corporate or public environments. 4. Limit app permissions to the minimum necessary, particularly for apps installed on Apple TV and other affected platforms, to reduce the risk of data leakage. 5. Educate users and administrators about the risks of installing unverified apps and the importance of timely patching. 6. Implement network segmentation for Apple devices to reduce exposure to untrusted networks and potential attackers. 7. Regularly audit device inventories to identify and remediate any devices running vulnerable OS versions. 8. Coordinate with Apple support and security advisories for any additional patches or mitigations.
